SLED-IRON.

Application filed May 7, 1917.

Z '0 all whom it may concern:

Be it known that I, SILAS L. Bosses, a citizen of the United States, residing at Hubbard Lake, in the county of Alpena and State of Michigan, have invented cer tain new and useful Improvements in Sled- Irons, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved sled iron, and has for its primary object to provide means fixed to the end of the beam to receive the vertically disposed bolts which connect the central portion of the runner brace to the runner, whereby lateral turning movement of the runner with respect to the beam is efiectually prevented.

It is another object of the invention to provide a sled iron which is so constructed to permlt of a vertical tilting or rocking movement of the sled runner with respect to the beam.

It is a further general object of the invention to provide a device for the above purpose which may be easily, quickly, and securely applied to the end of the beam, is strong and durable in its construction, and may be manufactured at relatively small cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective view of a portion of a sled runner and the end of the beam, showing my invention applied thereto;

Fig. 2 is a horizontal sectional view;

Fig. 3-is a section taken on the line 3-3 of Fig. 2; and

Fig. l is an enlarged perspective view of the sled iron.

Referring in detail to the drawing, R designates the sled runner and B the beam. It will be understood that the opposite ends of the beam are engaged centrally upon the spaced runners, and metal brace bars or struts S have their ends suitably fastened to the respective runners at opposite sides of the beam, the intermediate portion of the brace bar extending over the upper face of the beam.

To each side face of the beam 13, one of my improved sled irons, designated gen- S'pecification of Letters Patent.

Serial No. 166,9'21.

erally by the numeral 5, is secured. Each. iron consists of a rectangular metal casting having a rib 6 formed upon one face. The side of the beam is mortised or recessed, as indicated at B, to receive this rib, whereby shifting movement of the sled iron with respect to the beam is prevented. Upon the opposite face of the iron 5, spaced, parallel flanges 7 are formed, said flanges constituting the side walls of a substantially semicircular groove or channel indicated at 8. The base wall of this channel, as shown at 9, is longitudinally convexed, the highest point of said base wall being located at the center of the channel.

Vertically disposed bolts 10 are suitably fixed at their lower ends to the shaft and are seated in the channels 8 of the sled irons on opposite sides of the beam. Bolts 11 extending transversely through the beam, are engaged through coinciding openings in the sled irons on the opposite faces thereof, whereby said irons are rigidly fixed in place. The upper head ends of the rods 10 extend. through openings in the intermediate portion of the brace or strut S.

It will be apparent, from the foregoing description, that the rods 10 being engaged in the channels 8 of the sled irons will effectually prevent any lateral shifting move ment of the runner beneath the beam, while at the same time, owing to the convexity of the base Wall of said channel, the rods 10 may rock thereon in the vertical tilting movement of the runner when passing over obstructions or entering hollows or depressions in the road surface. By thus allowing for a vertical rocking movement of the runners with respect to each other, the movement will not be transmitted through the beams to the body of the sled which would result in considerable discomfort to the occupant thereof. My improved sled iron can be readily applied to the ordinary sled beam without requiring the services of a skilled mechanic, and as the device is in the form of a single metal casting, it is manifest that the same will be exceedingly strong and durable and can be manufactured at relatively small cost.

The device can also be made in various sizes and other means than that above referred to may be employed for catching or securing the iron to the beam. It will, therefore, be understood that while I have herein shown and described the preferred construction and arrangement of the several parts, the device is, nevertheless, susceptible of considerable modification therein, and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus fully described my invention, What I desire to claim and secure by Letters Patent is:

The herein described sled iron consisting of a metal casting having a relatively thick medial portion and side flanges adapted to be fixed to a sled bolster and being further formed with a longitudinally extending, rectangular rib projecting from one face of said medial portion for engagement in a mortise formed in the bolster, said sled iron being provided in the other side face of its media] portion With a longitudinally extending groove or channel having a longitudinal convex base Wall upon which a rod fixed in the sleigh runner is adapted for rocking engagement.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.
